To find the volume of a jar shaped like a cylinder (which is the typical shape of a peanut butter jar), we can use the formula for the volume of a cylinder:

\[ V = \pi r^2 h \]

where \( V \) is the volume, \( r \) is the radius of the base, and \( h \) is the height.

Given:

  • Height (h) = 16 cm
  • Width (diameter) = 10 cm, therefore the radius (r) = diameter/2 = 10 cm / 2 = 5 cm

Now, substituting the values into the formula and using \( \pi \) as 3.14:

\[ V = 3.14 \times (5)^2 \times 16 \]

Calculating the radius squared:

\[ (5)^2 = 25 \]

Now substitute that back into the volume formula:

\[ V = 3.14 \times 25 \times 16 \]

Calculating \( 25 \times 16 \):

\[ 25 \times 16 = 400 \]

Now multiply by \( 3.14 \):

\[ V = 3.14 \times 400 = 1,256 \]

Thus, the volume of the peanut butter jar is:

1,256 cubic centimeters.
